Description

A kind of peripheral band nibs cutting clamper
Technical field
The utility model relates to a kind of cutting clamper, is specifically related to a kind of peripheral band nibs cutting clamper, belongs to field of machining.
Background technology
Peripheral band is one of steam-turbine unit parts, and circular arc peripheral band is designed with several shroud nibs, the integral shroud of blade is assemblied in nibs.Shroud nibs requires that nibs position degree is not more than 0.2mm, and in the past during processing nibs, at nibs centre drill wire hole, then cutting on line lathe centering wire hole heartcut nibs, not only working (machining) efficiency is low, and machining accuracy is not high.
Utility model content
The utility model for solving existing banding pattern hole machined inefficiency, the problem that machining accuracy is lower, and then proposes a kind of peripheral band nibs cutting clamper.
The utility model is the technical scheme taked that solves the problem: the utility model comprises clamp body, two pressing plates, four holding screws and two alignment pins, peripheral band is arranged on the upper surface of clamp body by two pressing plates, and each pressing plate is connected with clamp body by two holding screws, two alignment pins are from top to bottom inserted on clamp body through peripheral band.
The beneficial effects of the utility model are: the utility model uses through reality, and effect is fine.During cutting shroud nibs, with clamp body conical recess location peripheral band, be positioned on the wire hole at two nibs centers after cutting processing nibs with two alignment pins, substantially increase machining accuracy, within making cutting rear profile hole location reach 0.1mm, accurately locate, without the need to carrying out centering to each nibs owing to adopting alignment pin, save a large amount of alignment time, improve working (machining) efficiency more than 30%.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model, and Fig. 2 is the top view of Fig. 1, and Fig. 3 is the structural representation of pressing plate, and Fig. 4 is the structural representation of alignment pin.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 and Fig. 2 illustrate present embodiment, a kind of peripheral band nibs cutting clamper described in present embodiment comprises clamp body 1, two pressing plates 3, four holding screws 4 and two alignment pins 5, peripheral band 2 is arranged on the upper surface of clamp body 1 by two pressing plates 3, and each pressing plate 3 is connected with clamp body 1 by two holding screws 4, two alignment pins 5 are from top to bottom inserted on clamp body 1 through peripheral band 2.
Have the conical recess of 167 × 5 ° in present embodiment in the middle part of clamp body 1, lay peripheral band 2 for location, 70 × 70 diamond hole positions align the nibs of cutting processing, and be greater than nibs, when being arranged so that cutting processing nibs like this, can not clamp body be cut to, improve cutting processing efficiency.4-M10 screwed hole coordinates with holding screw, by holding screw and pressing plate by peripheral band tight on clamp body.2-Φ 16 hole and detent fit, accurately navigated to peripheral band on clamp body by two alignment pins, when ensureing cutting processing, and the position degree requirement of each nibs.Both sides 20 × 20 boss coordinates with outer pressing plate, by outer pressing plate by tight on platen for this fixture handle.
Detailed description of the invention two: composition graphs 3 illustrates present embodiment, described in present embodiment, a kind of each pressing plate 3 of peripheral band nibs cutting clamper is all rectangle plate bodys, one lateral edges of each pressing plate 3 has multiple open slot 3-1, corresponding plug-in mounting holding screw 4 in each open slot 3-1.
The technology a short tale of present embodiment: so arrange, makes to be connected between holding screw 4 with pressing plate 3 more tight, can not slippage, improves positioning precision.Other composition and annexation identical with detailed description of the invention one.
Detailed description of the invention three: composition graphs 4 illustrates present embodiment, each alignment pin 5 of a kind of peripheral band nibs cutting clamper described in present embodiment is connected to form successively by cylinder 5-1 and handle 5-2 head and the tail, and the lateral wall of handle 5-2 is provided with anti-slip veins 5-3.
The technique effect of present embodiment is: so arrange, and increases the frictional force of handle 5-2 during operation, is easy to install and dismantle this alignment pin.Other composition and annexation identical with detailed description of the invention one.
